EECP or Enhanced External Counterpulsation is a non invasive outpatient treatment for refractory angina (chest pain that persists despite optimal medical therapy and is unsuitable for further angioplasty or bypass surgery) and other forms of chronic coronary artery disease. Inflatable cuffs wrapped around the calves, thighs, and buttocks compress in sequence with the heartbeat, increasing blood flow to the heart and reducing its workload. At Ramkrishna CARE Hospitals, Raipur one can access complete EECP assessment and structured treatment courses.
Symptoms of Diseases Requiring EECP
Patients referred for EECP typically have symptoms of chronic angina that have not responded fully to medicines or revascularisation.
- Stable angina presents as chest pain, tightness or pressure on exertion or emotional stress, often radiating to the arm, jaw, or back, and relieved by rest within a few minutes.
- Refractory angina describes the same symptoms persisting despite maximal antianginal medication, prior angioplasty and bypass surgery.
- Associated symptoms include breathlessness on exertion, fatigue, and reduced exercise tolerance.
Causes of Diseases Requiring EECP
EECP is recommended when the underlying cause of angina cannot be fully corrected by standard revascularisation:
- Diffuse coronary artery disease: Widespread atherosclerotic narrowing throughout the coronary arteries rather than discrete blockages often cannot be treated with angioplasty or bypass surgery because there is no single treatable segment.
- Microvascular disease: The dysfunction of the heart's smallest blood vessels (too small for angioplasty or stenting) and small-vessel disease are frequent indications.
- Prior multiple bypass surgeries or angioplasties: A history of multiple bypass surgeries or angioplasties with no further revascularisation options also leads to EECP referral.
Diagnosis of Diseases Requiring EECP
Diagnosis confirms the presence and severity of angina and establishes that EECP is an appropriate treatment option. Investigations are:
- Coronary angiography: An X-ray imaging procedure using contrast dye injected through a catheter confirms diffuse or non-revascularisable CAD
- ECG (electrocardiogram) and stress testing (treadmill or pharmacological stress echocardiography): These assess ischaemic burden (the extent of reduced blood flow to the heart muscle during exertion)
- Echocardiography: It evaluates LVEF (left ventricular ejection fraction - the percentage of blood pumped out with each heartbeat) and excludes significant valve disease, which is a contraindication to EECP.
Treatment
EECP is delivered as a structured outpatient course using ECG-synchronised pneumatic cuffs.
- During each one-hour session, three sets of pneumatic cuffs wrapped around the calves, lower thighs and upper thighs inflate sequentially from the legs upward during diastole (the heart's relaxation phase between beats), timed precisely to the patient's ECG. This increases venous return and diastolic blood pressure, improving coronary perfusion, while rapid deflation just before systole (the heart's contraction phase) reduces the heart's workload. A standard course comprises 35 one-hour sessions delivered over 7 weeks, five days per week.
- EECP promotes the development of collateral blood vessels (new small vessels that bypass narrowed segments) through repeated shear stress on the arterial endothelium (inner lining) and improves endothelial function (the blood vessel lining's ability to dilate appropriately). Most patients experience a reduction in angina frequency and severity, improved exercise tolerance and reduced reliance on nitrate medication by the end of a full course. Benefits typically build progressively over the final two to three weeks of treatment.
Risk of EECP
EECP is generally very safe but certain conditions increase procedural risk or are absolute contraindications:
- Severe peripheral artery disease: PAD or significantly reduced leg blood flow increases the risk of skin bruising, abrasion, or leg pain during cuff inflation and may require dose adjustment.
- Other Cardiac Conditions: Uncontrolled hypertension, decompensated heart failure, and significant aortic or mitral valve regurgitation increase cardiovascular risk during treatment.
- Active deep vein thrombosis: DVT or a blood clot in a leg vein is an absolute contraindication because cuff compression could dislodge the clot.
Complications of EECP
EECP has a low complication rate compared with invasive cardiac procedures, but minor adverse effects can occur:
- Skin bruising, abrasion, or blistering over the calves and thighs from repeated cuff inflation
- Leg or back discomfort during sessions
- Rarely, patients with unrecognised severe PAD can develop leg ischaemia (reduced blood flow).
Why Choose Ramkrishna CARE Hospitals for EECP Treatment in Raipur?
Ramkrishna CARE Hospitals, Raipur provides a dedicated EECP programme for patients with refractory angina and diffuse coronary artery disease unsuitable for further revascularisation.
Pre-treatment assessment here includes:
- Coronary angiography review
- Chocardiography
- Stress testing
- Peripheral vascular screening.
All these are done meticulously to confirm suitability and exclude contraindications such as significant valve disease or active DVT. Each EECP course is supervised by cardiologists and delivered by trained technicians using ECG-synchronised equipment with continuous monitoring of blood pressure and cardiac rhythm during every session. Angina severity, exercise tolerance and medication requirements are formally reassessed at the end of the course.
